Hello i am lookin for a nice mid-priced amp head. it can be tube . like 500 USD price range... I live in Turkey so i cant try most of them =( i will have to order from SAMASH (they ship to TURKEY) I heard : SansAmp - Gallien and Krueger - SWR - ASHDOWN - Trace Elliot (i guess they dont make it anymore ) - AMPEG. I am so confused cause i dont know anythin about all those brands. (no chance to test them =( COuld someone give me more info about them ? i want to use it in (U2 - Coldpay + Victor Wooten kinda stuff ) studio for rehearsals with loud drummer and maybe on big stages on the future.So high wattage is better i guess.... + i heard ADAM CLAYTON uses ASHDOWN heads. ALSO WHAT HEAD GO WITH WHAT COMBO ??
